Kickover tool

ABSTRACT

A kickover tool for running and retrieving equipment from a well in which a pivoted tool carrier is moved between a position aligned with the tool and a position misaligned with the tool by action of a key striking a shoulder on upward movement of the tool in a well. The pivotal tool carrier is latched in position during running of the tool and is unlatched and latched in the kicked over position upon upward movement of the tool upon the operating key engaging a shoulder in the well. The kicked over tool carrier is unlatched and returned to the latched aligned position by upward movement of the tool through the well.

KICKOVER TOOL This invention relates to well tools and more particularlyto a kickover tool for running and retrieving equipment from a well.

Kickover tools for landing and retrieving equipment from a well areexemplified by U.S. Pat. Nos.

2.664,]62; 2,679,903; 2,679,904; 2,828.698; 2,942,671; 2,948,341;2,959,227; 2,964,l l; 2.988.146; 3.075.586; 3.353607; 3,353,608; and

3,610,336. A primary disadvantage of-presently known kickover tooldesigns is that a spring is utilized to move the tool carrier intokicked over position. With highly deviated wells. these springs must bevery heavy to move the tool carrier into kickover position when the toolcarrier has to lift the tool against the force of gravity. Thus oneobject of this invention is to eliminate the action of springs in movingthe tool carrier to kicked over position and to provide for kicking thetool over with a solid metal force transmission linkage which isactivated by pulling up on the tool after the locator key is against thestop shoulder in the well.

Another problem with the previous kickover tool designs is theirdependence on the kickover spring to hold the tool in kicked overposition while the tool is manipulated to either seat or retrieveequipment. Another object of this invention is to eliminate this problemby providing for latching the tool carrier in the kicked over positionduring operation of the tool to land or retrieve equipment. A corollaryobject is to provide overriding means for the simple release of themechanism for latching the kickover tool in kicked over position.

The locator keys of the prior art commonly are sheared off when pullingthe tool from the hole. To accommodate the sheared keys requires spaceor some complex mechanism to permit it to remain in the retractedposition. An object of this invention is to provide a running tool inwhich the locator key support is not sheared and the key retracts duringupward movement ofthe tool by having its upper end chamfered and the keyfunctions to engage in the well on upward movement by having a shoulderat the upper end of the key which is pinned in position duringmanipulation of the tool but which is sheared to fall freely about itspivot to an out-of-the-way position when the tool is removed from thewell.

Another object is to simplify the construction of the tool by providinga single spring for loading the latch mechanism and urging the locatorkey support or plunger toward its upper position.

Another object is to provide a kickover tool in which the tool carrieris latched in both its positions in alignment with the main body of thetool and in its kickover position.

Another object is to provide a kickover tool in which a knuckle joint isprovided in the tool carrier and while being spring loaded towardaligned position it can rotate to a position in which the tool beinglanded or retrieved is substantially parallel to the main housing of thetool while the tool carrier arm is in kicked over position.

A characteristic of the kickover tools of the prior art is that once thetool carrier is released and kicked to the kickover position it isspring loaded toward this position until the tool is removed from thehole. Another object of this invention is to provide a kickover tool inwhich after the tool carrier has been moved into misaligned or kickedover position to land or retrieve well equipment, upward movement of thetool results in relatching of the tool carrier in aligned position sothat thereafter the entire tool may be freely run up or down in thewell. This is of particular advantage in preventing the tool frombecoming stuck as it is retrieved from the well. Also, the realignmentof the tool carrier reduces wear on the tools as they are retrieved fromthe well.

Another object is to provide a kickover tool which may be redressedafter it has been run by replacing a single shear pin.

Another object is to provide a housing or housing and upper sub ofsufficient length to serve as a guide for the kickover tool.

Other objects. features and advantages of the invention will be apparentfrom the drawings, specification and the claims. In the drawings whereinlike reference numerals indicate like parts and wherein an illustrativeembodiment of this invention is shown:

FIG. 1 is a view in cross section through a well tubing and side pocketmandrel showing therein in elevation at kickover tool constructed inaccordance with this invention;

FIGS. 20 and 2b are a continuation of views in cross section of thekickover tool shown in FIG. 1;

FIG. 3 is a fragmentary view in cross section showing the relationshipof the parts when the tool is in kickover relationship.

The tubing string has therein a plurality of side pocket mandrels. afragment of one of which is shown at 11. The portion of the side pocketmandrel which is not shown is conventional in form and the tubing stringwould normally be run with a number of such mandrels at spaced pointsalong the tubing. The tubing will be in the casing ofa well forproducing liquids. The well casing and well are not shown for simplicityof illustration.

At the upper end of the side pocket mandrel ll a shoe 12 having a slopedlower surface 13 for orienting the tool is shown. The sloped surface 13terminates in a vertical slot 14 having a shoulder 15 at the upper endof slot 14. As will appear more fully hereinafter the kickover tool isactuated by engagement of the key 16 with the shoulder 15.

The locator key 16 is carried in an elongate housing 17 which issuspended from the wireline sub 20 which is carried on wireline tools26. The sub is longer than usual and cooperates with the housing 17 toserve as an aligning guide for the tool. If desired, conventional jarsmay be employed. Pivoted from the elongate housing 17 is the pivot arm18 which carries on its lower end through a suitable knuckle jointindicated generally at 19 a lower adapter 21. The lower adapter carriesa conventional running or retrieving tool indicated generally at 22. InFIG. 1. the tool is shown to be supporting a valve 23. While the tool 22is of a different form in running and retrieving equipment, therelationship of the valve or other equipment 23 to the remainder of thetool will be the same. As in conventional in this type of equipment, thevalve is landed in the valve receiver 24 and a suitable latch cooperateswith shoulder 25 to maintain the valve in the side pocket mandrel.

Referring now to FIG. 2a. the elongate housing 17 is shown to be tubularin construction and threadedly connected to the wire line sub 20. Withinthe bore 27 of the elongate housing 17, there is positioned a plungerelement 28 which carries the locator key 16 and provides a non-elasticmeans for kicking over the pivot arm 18.

To carry out the kickover function, the lower end of the plunger 28 hasan abutment surface 29 thereon. which engages a complimentary abutmentsurface 31 on the upper end of the pivot arm 18. it will be noted thatthe surface 31 is spaced laterally from the pivot 32 on which the pivotarm 18 is supported. Thus downward movement of the plunger 28 willresult in rotation of the pivot arm 18 from its position in alignmentwith the elongate housing 17, as shown in FIG. 2a to a position ofmisalignment or the kickover position as shown in FIG. 3.

In order to provide for downward movement of the plunger 28 relative tothe elongate housing 17, the locator and orienting key 16 is provided.This key is pivoted about pin 33 and urged to an extended position bythe spring 34. The key 16 is chamfered on its upper and lower ends asshown at 16a and 16h. An abutment member 35 is carried by the key 16 andis rotatable about pin 36. 1t is held in the position shown in FIG. 2:1by a shear pin such as brass pin 37. In running the tool downwardly intothe tubing 10, the chamfer 16a of key 16 will ride over any obstructionsin the well and permit free movement of the kickover tool downwardlyinto the well to the desired level. Thereafter upward movement of thekickover tool will result in the shoulder member 35 of the key 16engaging the orientating surface 13 (FIG. 1) and directing the keyupwardly into slot 14 until it engages the shoulders 15. Further upwardmovement ofthe tool will result in upward movement ofthe elongatehousing 17 relative to the plunger 28 as upward movement ofthe plungerwill be arrested. thus resulting in rotation of the pivot arm aboutpivot 32.

After the tool has been utilized to land or retrieve a well tool. thekickover tool is returned to the position shown in FIG. 1, in which thekey again engages shoulder ]5. A strong upward jar or pull results inshearing ofpin 37, permitting the member 35 to swing about the pivot 36into an out-of-the-way position. Thereafter the chamfcr 161) will causethe key 16 to retract as the tool moves upwardly in the well to permitthe ready removal of the tool from the well. A stop pin or shoulder 38is provided to prevent the member 35 from swinging to the left of theposition shown in FIG. 2a.

Latch means are provided for maintaining the pivot arm in both itsaligned position during running of the tool, and in its kicked overposition while the well tool is being landed or retrieved from the sidepocket. A pair of confronting shoulders provides the latch means to holdthe pivot arm 18 in alignment with the elongate housing 17, duringrunning of the tool. A finger 39 on the pivot arm extends upwardlybeyong the pivot pin 32. This finger is provided with a projectingshoulder 41. which cooperates with the shoulder 42 on the plunger. Asshown in FIG. 2a, these cooperating shoul ders confront each other andprevent rotation of the pivot arm from aligned to kickover position.Rotation of the pivot arm in the opposite direction is prevented byconfronting shoulders 43 on the lower end of the elongate housing 17 and44 on the pivot arm 18.

The latch provided by the confronting shoulders 41 and 42 is released bymovement of finger 39 upwardly with the housing 17 relative to plunger28 to a position in which the shoulder 41 extends into a groove 45 inthe plunger 28, thus permitting rotation of the pivot arm 18 about thepivot 32 to the position shown in FIG. 3. It will be appreciated that atany time that the key 16 is inoperative to prevent upward movement ofthe plunger and the pivot arm 18 has been returned to its position inalignment with elongate housing 17, that the plunger 28 is free to moveupwardly under the influence of spring 46 and permit reengagement of theshoulders 41 and 42 to again lock the pivot arm in a position inalignment with the housing 17.

As noted above, latch means is also provided to latch the pivot arm inits kickover position in which it is rotated or misaligned relative tothe elongate housing 17. This latch means is provided by a latchshoulder 47 on the finger 39, which cooperates with a latch member 48carried by the plunger 28. The latch 48 is pivotally supported on theplunger 28 by pivot 49. The latch 48 has a downwardly extending portionwhich provides the shoulders 51 and 52. The upper end 53 of finger 39abuts the downwardly facing shoulder 52 of the latch 48 and holds thelatch in disengaged position while the pivot arm is in alignment withthe housing 17. However, when the pivot arm is rotated about the pivot32 by upward movement of the elongate housing 17 rela tive to theplunger 28, the shoulder 51 passes over the end of finger 39 and thelatch member 48 drops down to the position shown in FIG. 3 in which theshoulders 51 and 47 are in register, and prevents return of the pivotarm 18 to its aligned position.

The latch member 48 is urged into the down or latched position by thespring 46, acting through the spring guide 54 and the spring guide head55 which bears against the upper surface of the latch 48. The latchpivot 49 is spaced longitudinally of the housing from the point ofcontact of shoulders 47 and 51. This results in a moment arm equal tothe distance of the pivot above the point of contact ofshoulders 47 and51 through which force is applied in a counter clockwise direction whenthe arm 18 is urged toward aligned position. It will be noted that whenthe surfaces 51 and 47 are in engagement to retain the pivot arm inkickover position (see FIG. 3), these surfaces preferably diverge in anupwardly direction, that is, in a direction toward the main body of theplunger 28 and key 16 to provide a line contact between surfaces 47 and51. Thus, the shoulder 47 acts as a ramp along which the lower extremity of shoulder 5] slides, and by exerting a force on the pivot armsufficient to overcome the force of spring 46, the latch member 48 willbe forced upwardly to permit the pivot arm to realign itself withelongate housing 17 for removal of the tool from the hole.

The knuckle joint shown in FIG. 2b is provided to hold the equipmentbeing run into the hole in align ment with the pivot arm while the toolis being run or retrieved but at the same time providing for a rotationof the lower adapter 21 to a position approximately paralleling theelongate housing 17 as shown in FIG. 1 in response to the equipment suchas valve 23 being in engagement with the side-pocket mandrel 11. Thelower adapter 21 is pivoted to the pivot arm 18 by a pivot member 56.The upper surface 57 of the lower adapter 21 is formed at a slight angleto the longitudinal axis of the lower adapter 21. The lower surface 58of the pivot arm is formed perpendicular to the longitudinal axis of thepivot arm. The pivot 56 is offcenter. and on the short side (at 19) ofthe assembly relative to the pivot 56. The surfaces 57 and 58 are inengagement to hold the lower adapter in alignment with the pivot arm andprevent further rotation in a counter-clockwise direction as viewed inFIG. 2b. The parts are urged into this relationship by a spring 59,acting on ball 61, which is in engagement with the surface 570. When thearm 18 is kicked over and a well tool engages the side pocket wall. thelower adapter 21 may rotate clockwise as viewed in FIG. 212 against theforce of spring 59 until the surfaces 57a and 58 come into engagement onthe long side of the lower adapter relative to the pin 56, and limitmovement in a clockwise direction to a relatinship in which thelongitudinal axis of the lower adapter 21 is approximately parallel tothe longitudinal axis of the elongate housing 17.

In operation, the tool is dressed by inserting a new pin 37 in the key16 and shoulder member 35. Assuming that a well tool is to be run asuitable adapter is provided and secures the well tool to the lower sub21. The several parts will be in the relationships shown in FIGS. 2a and2b. The tool is run into the well on the wire-line, or ifdesired, withsuitable pump down equipment until the tool is positioned below theorienting shoe 12. Reverse force is then applied to raise the tool untilthe key [6 slides along the orienting surface 13 and up through slot 14into engagement with shoulder 15. Further upward pull results in upwardmovement of the housing 17 relative to the plunger 28 to disengage theshoulders 41 and 42 of the latch means and rotate the pivot arm [8 in acounter-clockwise direction to the position shown in FIG. 3. At thistime. the latch 48 will drop down under the force of spring 46 andengage shoulder 47 to latch the pivot arm in the kickover position. Thewell tool being run will have engaged the side wall of the side pocketmandrel, and have rotated the lower adapter against the force of spring59 (FIG. 2b) to the position shown in FIG. 1. As the pivot arm is heldin this position. the entire tool may be lowered to seat the well toolwithout the application of substantial side forces to the tool beinglanded.

After the well tool is landed, the attaching means is released in theconventional manner and the tool is moved upwardly in the mandrel. Afterthe key 16 has again engaged shoulder 15, a substantial jar force isexerted on the tool to shear the pin 37 and release the shoulder member35, thus permitting the upper chamfer 16b to be effective and retractthe key as the tool is pulled up the hole. When the pivot arm 18 comesinto contact with the upper section of the side pocket and the orientingsleeve 12. a force is exerted on the pivot arm 18 which overcomes theeffect of spring 46 and straightens out the pivot arm and returns it toits latched position in alignment with housing 17. As the pivot arm 18is straightened out. the shoulder 47 on the upper end of finger 3) actsto force the latch arm 48 up until it is in an inoperative orineffective position and permit the pivot arm to rotate to fullalignment with the housing 17. At this time the lower end of theshoulder member 41 clears the groove 45 to permit the plunger to moveupwardly again under the force of spring 46 and again bring into theconfronting positions the surfaces 41 and 42. At this time the pivot arm18 and lower sub 21 are again secured in alignment with the housing 17and the tool may be pulled from or lowered through the hole withoutdragging the pivot arm or the tool that may be on the end thereofagainst the well tubing all the way to the surface.

The operation is the same in retrieving a tool, except that a differentattachment is secured on the lower adapter 21 and is run into a positionin which it is secured to the upper end of a well tool in theside-pocket mandrel.

It will be appreciated that as the entire tool has all of its parts inan aligned position and the key 16 is chamfered on both its upper andlower end that the tool may be moved upwardly or downwardly in the holeat any time by the operator. Thus, if difficulty is encountered inpulling the tool from the hole, it may be lowered to a position belowthe obstruction without fear of the tool becoming caught in any portionof the tubing to give the operator freedom of movement of the tool toassist in retrieving the tool from the well.
